What are the key differences between parametric and non-parametric tests? Provide one example of a parametric test and one example of a non-parametric test.

Janet, after years of working as a hairdresser and as a makeup artist, decided to go into business for herself. Over time the business has grown into a spa and beauty retreat and she now employs a few staff. With her growing operation she has identified the need to implement a computerized accounting information system. In order to have a system that meets her needs exactly and also to save cost, she has asked you to create a simple, customized solution for her business. Her immediate need is for a customer sales information system, so that is what you will now create. With customer service being so important to Janet, her customers tend to become regulars and she wants to maintain a record of each customer’s contact information and preferences so that the spa will know what is important to the customer without having to be told each visit. The customer information that Janet considers important to maintain is the full name, cellphone number, favourite treatment, and special considerations (e.g. some customers have allergies or require fragrance-free products). For employees, Janet just needs to record the names and cell phone numbers in the database. The spa also has a standard list of services which each have a standard name, description and price. Janet also wants a database record of each customer visit both for customer billing at the time of service, as well as for future analysis. Janet wants to refer to these sales transactions as “Visits” in the database in order to reflect the spa’s focus on customers’ experiences. For each of these customer visits it is important to record a unique visit identifier, the date, the customer, the main staff member who served the customer, and the service or services experienced (sold).

I am working on a project for my business class to creat a non profit organization! I came up with offering free WIFI/internet to everyone in the comfort of their own homes (without having to run to starbucks everytime you need to look something up) I am having trouble answering these two questions regarding my non profit so any advice would help!

5. Describe the type of legal structure that would be most appropriate

for the non-profit organization.

6. Discuss an event that could be done to help fund the non-profit.

Consider this class with a const variable and function:
class Student {
private:
const int IDNum;
public:
Student();
int getIDNum() const:
};
a. How do you initialize the const variable IDNum to 100? Write the code:
b. Are getters normally declared const?
c. Are setters normally declared const?
d. Can a const function call a non-const function?
e. Can a non-const function call a const function?
f. Can a const function use a non-const variable?
g. Can a non-const function use a const variable?

A medical study, a doctor is interested in determining what factors affect forced expired volume values (FEV). The doctor randomly samples 15 patients and records their smoking status and age. Using the data, create the regression output (including the y-intercept and both independent variables) then answer the questions below. Note that smoking status and age are recorded as categorical variables.

• Write out the estimated regression line. To receive full credit, you must label all variables/categories.

• Run an overall F-test to determine if the multiple regression model is significant at a 5% significance level. To receive full credit, you must give me:

• Predict the FEV value for a smoker over 50 years old.

• Estimate the average FEV for non-smokers between 30-40 years old.

The Nowra Company has assembled the following data pertaining to certain costs that cannot be easily identified as either fixed or variable. Nowra Company has heard about a method of measuring cost functions called the high-low method and has decided to use it in this situation.

How is the cost function stated?

The Yeppoon Company uses the high-low method to estimate its cost function. The information for 2018 is provided below:

What is the constant for the estimating cost equation?

The cost components of an air conditioner include $35 for the compressor; $11.50 for the sheet moulded compound frame; and $80 per unit for assembly. The factory machines and tools cost is $55 000. The company expects to produce 1500 air conditioners in the coming year. What cost function best represents these costs?

V8 Engineering Pty used the following data to evaluate their current operating system. The company sells items for $14.50 each and had used a budgeted selling price of $15 per unit.

                                                                   Actual             Budgeted
        Units sold                                   206 000 units      200 000 units
        Variable costs                            $965 000               $950 000
        Fixed costs                                    $53 000                 $50 000

What is the static-budget variance of variable costs?

You are a partner in a medium-size CPA firm and want to convince your partners that your firm should update the way it conducts audits in order to become more competitive. Specifically, you believe the company should make use of up-to-date data analytics technology. Write a memo to your partners to explain what data analytics technology is and the advantages to using it. Chapter 10 (From Effective Writing A Handbook for Accountants by May) contains suggestions on memo organization and format. Submit your paper in PDF format and see Syllabus naming convention.

How to code the following function in C? (NOT C++)

int vehicleInsert(HashFile *pHashFile, Vehicle *pVehicle)

This function inserts a vehicle into the specified file.

• Determine the RBN using the driver's hash function.

• Use readRec to read the record at that RBN.

• If that location doesn't exist or the record at that location has a szVehicleId[0] == '\0': o Write this new vehicle record at that location using writeRec.

• If that record exists and that vehicle's szVehicleId matches, return RC_REC_EXISTS. (Do not update it.)

• Otherwise, return RC_SYNONYM. Note that in program #2, we will actually insert synonyms.
